[ITK-users] GPU Implementation

[Xiaopeng Yang]

Hi Jim,

 

Thanks for your suggestion. I tested with a smaller dataset: 512 × 512 × 75 and it worked. No crash occurred. 

 

Best regards,

Xiaopeng

I'd start by using a smaller dataset. Perhaps downsample your dataset to 256x256x150 to see if that works on your card.

Hi Jim,

 

So you mean I need to change graphics card or set some parameters? How to allocate the memory of graphics card? 

 

Thanks,

Xiaopeng

I estimate that you would need over 2GB on your graphics card to run the demons algorithm on that size of a dataset.

Dear Jim,

 

The images are quite large: 512 * 512 *300. 

 

I did not build test when I compile ITK.

 

Thanks,

Xiaopeng

How large are the images that you are using?

Hi John,

 

Sorry I mean the program got crashed after showing #define T float. 

 

Thanks,

Xiaopeng

Dear Jim,

 

Thanks for your help. I built the test successfully, but I met an error when I run the program. Please see the attached image file. 

 

Best,

Xiaopeng

Is that an error?
